HELP PLEASE -creating dvd files

I am using clone dvd 2 and any dvd. I am new at copying - but when I first started using the program to burn a dvd it would take approx 20mins - now it is taken approx 2hrs!

help - any suggestions on how to fix this?

sorry, I posted this question in the wrong forum. I have had this question answered in another forum. my channels were set to pio mode for transfer not dma mode. this has since been reset and I am back to 20min burns.
